the side walls of this end member and pro-,

viding a hollow'center portion in the abut ting surface of the endmember to receive the 1 rojecting attaching eye member on the watchcaseto which this'end member may be attached by a locking pin to disposethese end inoinbers on a downwardly inclined angle to the plane oi theface of the watch. \Vith these and other ob ects in view, the

- invention consists of certain novel features of construction, as willbe 'more fully described, and particularly pointed out in the appendedclaims' I In the accompanying drawings: r Fig. 1 is a face view of thewatch showing my improved watch strap with its end members secured toopposite sides thereof. Fig. 2 is an edge View of thewatch show ingthoattaching eye members on the opposite sides'thereof.

Fig. 3 is a plan View of one of the end members.

Fig. 9 is a section on line 99 of Fig. 8

showing the end member as pinned and so rigidly secured to the watchcase.

Fig. 10 is a side elevation showing the width of the end member wristwatch strapwith end members secured at a downwardly inclined angle toopposite sides of the watch case. It s iound inpractice of advantagetoprovide a watch strap with metal 'end mem hers each of a configurationand finishto harmonize with that of the watch case and so shaped as topresentthe appearance of being a part of the watch case as such aconstruction imparts to the watch and strap a higher artistic" valuethan where the end members do not abut or set close against the watchcase and which, therefore, cannot pie{ sent the continuity of shapepresented by my improvedconstruction. To accomplish this result in asimple and effective way, I have formed one of the extremities oi? eachof these end pieces with its walls disposed at an incline to the planeof the end piece and I have provideda central opening in the end of thisend piece to receive the eye member be secured to tl'iejwatch case byforcing a lockingpinthrough the walls of the end vpiece and through theeye'onthe'watch case; I

and the following is a detailed description of the present embodiment ofmy invention and i showing one means by which these advantageous resultsmay be accomplished:

Nithieierence to the drawings, 10 designates the watch case which may bemade in any suitable form and to this watch case I have securedattaching eye memb'ers 11,-the length of which is preferably less thanthe end members each comprises a body portion g having a top wall 15 andside walls 16, and

in order to providea more extended bearing surface on the extremity ofthe end member and to also support and reenforce the stock j of the bodymember, I have provided a brace plate 17 which is formed of stocksomewhat heavier than that of the body portion. This brace plate isprovided with so as to fitbet-weeii ioo side flanges 18 which fitssnugly between the side walls 16 f the body member, and the body of theplate itself is set on an angle to the plane of the body member tobetter serve as a brace and reenforcement of the stock of the body. vThis brace plate is then secured in position by being soldered therein.The side walls 16 of this body member together with these side flanges18 of the brace plate 17 are pierced as at 19, see Fig. 7, to receivethe lock pin 20, see Figs. 8 and 9, the end walls of this end member areI then cut or shaped to set on an incline to the surface of its bodyportion and by this arrangement or the brace plate with its side flangesa central opening 21 is provided within the outline of these walls andflanges which opening-is designed to receive the eye member on the watchso as to permit this end member to be set with its extremity abuttingagainst the side wall of the watch case and whenpinned into position bythe appearance not found in the usual detachable watch book; also thisconstruction eliminates the possibility of accidental detachment fromthe watch.

The foregoing description is directed solely towards the constructionillustrated but I desire it .to be understood that I reserve theprivelege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims. 1 I claim:

1. A wrist watch strap having metal end members each comprising a bodyportion with top and side Walls, a brace plate having inturned edgewalls fitting between and secured to the side walls of theend member,the end bearing surfaces formed by the combined walls. of said bodymember and brace plate beingset on an incline to the plane of the body,and said end walls and edges in outline forming av hollow center portionfor the reception of the engaging eye on the watch case, and means insaid body for securing it rigidly to the watch brace plate being setonan incline to the plane of the body, and said end walls and edgesinoutline forming a hollow center portion for the reception of theengaging eye on the watch case, the side walls of said brace platemember being pierced to receive a lock pin to extend through an eye inthe watch case to rigidly secure said end members to the case on anincline to theface of the watch.

3. ,A wrist watch strap having an end member comprising a body portionwith top and side walls, and a brace plate having inturned edge wallssecured to the side walls of the end member and its body between theinturned edge walls disposed at an'angle to "the top wall of the saidend member.

A. An end member for wrist watch straps comprising a body portion withtop and side walls, the front edges of'which are in clined inwardly fromthe top wall, and means for reinforcing the open end of the said end.member including a brace plate having inturned edge walls secured tothe sides of the said member and its body between the said inturnededgewalls forming a bottom at the front of the said end member. .7

.5. An end member for wrist watch straps comprising a body portion withtop and side walls, the front edgeso'f which are inclined inwardly, fromthe top wall, and means forreinforcing the open end of the said endmember including a brace plate having inturned edge walls secured to thesides of the said member and its body between the said inturned edgeWalls forming a bottom at the front of the said end meniber, the front.edgesof the said brace plate being inclined to correspond with the frontedges of the said end member.

' In testimony whereofI afiix my signature.
